722 FUMARIACE. 
Bocconia is said to be apetalous, if so, so may be Fumaria- 
cez, the development and origin of the envelopes is perhaps 
rather calycine than petaline, but the subject is so difficult 
as to require extensive examination, Papaveraceze cannot be 
well understood, the two-leaved calyx and 4-leaved corolla 
requiring satisfactory explanation. We might combine Fu- 
mariacee with Papaveracee because of Hypecoum which is 
another instance of incongruous inconsistency. If it ought 
to be done, then we ought to treat similarly all intermediate 
forms.
